TMF637 v4 Product Inventory Management API
The Product Inventory Management API (TMF637) provides a standardised mechanism to retrieve product inventory information.
The Product Inventory Management API is certified by TM Forum.
- For TMF Open API release and specification version, see Industry API Version.
For the Spring'26 and Summer'26 releases, TMF637 v4 API can be accessed using either of the following methods.
- Mule Gateway: Access API through standard MuleSoft endpoints. For sample URLs, payloads, and parameter descriptions, see Reference section for details on TMF637 v4 MuleSoft endpoints.
- Direct Access: Bypass Mule Gateway using Connect/Apex REST endpoints.
- See TMF637 v4 Use Cases section for sample URLs and payloads.
- See TMF637 v4 Resource Mappings section for parameter descriptions.
Starting from the Winter ’27 release, only the Direct Access option will be supported. The MuleSoft gateway option will be deprecated, and customers must update their integrations to use the Connect/Apex REST endpoints for continued access to the inbound APIs.
This API is available in the managed package.
